Embodiment 1

[0049] Embodiment 1: see figure 1 , The convex vacuum glass is composed of an upper glass 1 and a lower glass 2, the peripheries of the two pieces of glass are welded together by low-temperature glass solder 4, and the middle is a vacuum layer. Its production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the convex vacuum glass produced, drill a through hole at the corner of the upper and lower glass respectively to form an air inlet and a mounting hole 3, and place a hole around the lower glass 2. and the periphery of the air outlet 3 to provide a sealing groove 6, and carry out edging, chamfering, cleaning and drying, and use mechanical spraying technology to prepare the sealing strip 5 at the peripheral welding place of the upper glass 1 and the periphery of the air outlet 3, and use a glue dispenser Prepare the support 8 on the upper and lower glass; secondly, put the upper and lower pieces of glass into t...

Embodiment 2

[0050] Example 2: see figure 2 The convex vacuum glass consists of an upper glass 1 and a lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass. The production method is as follows: firstly, cut the convex vacuum glass according to the shape and size of the convex vacuum glass. A piece of flat glass and a piece of low-emissivity glass of the required size, choose the low-emissivity glass as the lower glass 2, drill a through hole at the corner of the upper and lower glass respectively to form the air inlet and the installation hole 3, and place a hole around the lower glass 2 and the air outlet 3 Set up a sealing groove 6 on the periphery, and perform edging, chamfering, cleaning and drying, and use screen printing technology to print sealing strips on the peripheral welding part of the upper glass 1 and the periphery of the air inlet 3; secondly, put the two pieces of glass into the In two forming molds, the fo...

Abstract

A piece of vacuum convex glass welded with seal grooves and mounting holes includes a piece of upper glass and a piece of lower glass, and is characterized in that the mounting holes and extraction openings are integrated; the upper glass and the lower glass are convex glass; seal strips are arranged on the peripheries of the upper glass and the extraction openings; the seal grooves are formed in the peripheries of the lower glass and the extraction openings; the peripheries of the upper glass and the lower glass are welded in an ordinary pressure lower edge sealing furnace through low temperature glass solder; the extraction openings are automatically sealed in a vacuum furnace through metal solder; a sealed vacuum layer is formed between the upper glass and the lower glass. The vacuum glass and the manufacture method, provided by the invention, have the advantages that the technology is simple, the manufactured vacuum glass and the toughened vacuum glass facilitate mounting and use, the airtightness of the vacuum glass is guaranteed, and intensity as well as heat and sound insulation performance of the glass can be improved.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a convex vacuum glass welded with sealing grooves and mounting holes and a manufacturing method thereof. [0002] Background technique [0003] Vacuum glass is a new type of energy-saving glass. Vacuum glass can not only solve the "breathing" problem of insulating glass used in large quantities, but also has good heat and sound insulation performance, high wind pressure resistance, small thickness and long service life. advantage. Vacuum glass is generally composed of two to three pieces of glass, a cavity is formed between two adjacent pieces of glass, and an edge sealing structure is arranged around the glass, and the cavity is evacuated to form a vacuum layer. Vacuum glass can be divided into two types according to the way of forming the vacuum layer. One is the vacuum glass without exhaust port. The edge sealing of this vacuum glass is carried out in a vacuum ...
